HX Series Remote Condenser Site Preparation and ... - Chiller City

Remote CondenserThe remote condenser should be located on a well-constructed, level surface,able to withstand the distributed weight of the condenser and the mountinghardware. The ambient temperature of the site should be within the range of-10°F to +110°F (-23°C to +43°C).Remote condensers for HX-150s, HX-200s, and HX-300s are available withvertical airflow only. Condensers for HX-500s, HX-750s and HX-900s areavailable with either horizontal or vertical airflow.Vertical airflow units should be located no closer than the width of the unitfrom a wall or other obstruction. Increased distance is preferred wheneverpossible. Sufficient free area should be left around and below the unit to avoidair restriction to the coil.For multiple units placed side by side, the minimum distance between theunits is the width of the largest unit. If the units are placed end to end, theminimum distance between the units is four feet.If the unit is placed in a pit, the top of the unit should be level with the top ofthe pit and the side distance increased to twice the width. If the top of the unitis not level with the top of the pit, discharge cones or stacks must be used toraise discharge air to the top of the pit. This is a minimum requirement.If the unit is placed behind a fence, the fence must have a 50% free area,with a one foot (minimum) undercut. The unit cannot be closer than the widthof the unit to the fence, nor should the top of the fence exceed the height ofthe unit. If these requirements are not used, the unit must be installed like aunit in a pit.Horizontal airflow units should be installed with the coil (inlet air side) facingthe prevailing winds. If the coil faces a wall, there must be a minimum clearanceof 4 feet (1.2 meters) for adequate air flow. Increased distance ispreferred whenever possible.Inadequate air flow will cause a reduction in cooling capacity and, inextremecases, refrigeration system failure.The remote condenser must be securely mounted to the foundation on whichit is installed (concrete pad, rooftop, etc.). The condenser frame has holesthat allow the condenser to be lag bolted to its foundation. Refer to Figures1 through 6 to identify the minimum pad size and the bolt pattern details foryour remote condenser. Concrete slabs used for unit mounting should beinstalled level and be properly supported to prevent settling. We recommenda one-piece concrete slab with footings extended below the frost line.- 8 -
